[Dovecot] Disconnected: Too many invalid IMAP commands
by Gabriele 02 Oct '09

02 Oct '09

Greetings, I'm having big issues here, hope you can help me… Ubuntu Server 8.04, postfix 2.5.1, dovecot 1.0.10, postfixadmin (MySQL+ virtual users)… I am trying to move e-mails from an old IMAP account to my new dovecot IMAP server accounts. The old server is EIMS (Eudora Internet Mail Server, so a sort of mbox format)… I move messages by drag 'n' dropping in Mozilla Thunderbird. No problems with messages under 4MB size (there are huge messages, up to 25MB), but as soon as I try to move messages from 4MB and up, the connection hangs, nothing happens, the application becomes barely responsive, I have quit and re-open it to make it behave properly. In the logs, I read (user and IPs are fake, here): Sep 18 07:52:06 in dovecot: imap-login: Login: user=<user@my-domain>, method=PLAIN, rip=123.123.123.123, lip=123.123.123.123 Sep 18 07:52:06 in dovecot: IMAP(user@my-domain): Disconnected: Too many invalid IMAP commands. Could it be a client (Thunderbird) issue? I have tried with Apple Mail 4.1, same problem, same logs. Could it be a quota limit (googling around, I read that sometimes the error may be triggered by dovecot when exceeding the quota limit) Accout usage is actually at 1%… Could drag 'n' drop be the wrong way to have things done? I have also downloaded the huge e-mails from EIMS to Thunderbird Local Folders, the problem arises when I try to upload, so the culprit seems to be the new "system". I really need help at this point… any hints? Thanks in advance for any help you will offer. Gabriele

[Dovecot] Password and special caracter
by Gilles Albusac 02 Oct '09

02 Oct '09

Problem : I have a problem with special character in the password. Character like ! * é are deleted My configuration : - a smtp server with Postfix 2.6 and Dovcot 1.1.11. - a windows 2003 server with active directory for accounts and boxes I use SMTP / SASL on my postfix 2.6 to authenticate my remote laptop users (allow legitimate users to relay mail). To do that, I use SASL Dovecot fonctionnality and ldap request to verify login/password who are declared on a server in Windows 2003 (Active Directory). It works fine with simple password but not with complex password. I have a problem with special character in the password. Character like ! * é are deleted before comparaison. Any idea ? Regards

[Dovecot] I can acces my pop3 account but I can't send an email trough smtp
by Ricky Tompu Breaky 01 Oct '09

01 Oct '09

Dear my friends.... I use OpenSuSE 11.1, KMail and DoveCot version: " sussy:/etc/ssl/certs # dovecot --version 1.1.7 ". This is the configuration of my DoveCot: " sussy:/etc/ssl/certs # dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.29-0.1-default i686 openSUSE 11.1 (i586) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: imap imaps pop3 listen(default): * listen(imap): * listen(pop3): *:110 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: Dovecot of MyGoogle.Com ready. mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: debug_passwords: yes passdb: driver: pam userdb: driver: passwd ". I have created local linux user account on my Postfix+DoveCot server. I also can access the content of my mailbox from my KMail. I am so happy but once I try to send email (testing the smtp) than I realize that I can't send an email from my email client (KMail). I use this setting on my email client: 1. 'incoming mailserver' == 'outgoing mailserver' == 'mail.mygoogle.com' (pseudonome). Also username and password are all the same between incoming/outgoing mailserver, namely the local userlogin of LINUX. As the username, I put 'ricky' (but not 'ricky(a)mygoogle.com'). 2. smtp authentication: No encryption and plaintext. The error message on my KMail is: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method. The server responded: "5.7.8 Error: authentication failed: generic failure" The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport was used: mygoogle.com Do you want me to continue sending the remaining messages? " and also: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method. The server responded: "5.7.8 Error: authentication failed: generic failure" The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport was used: mygoogle.com ". I'm stucked again. Please help me. Tell me where my mistake. Thank you very much in advance.

[Dovecot] Encryption Plugin
by Patrick McLean 01 Oct '09

01 Oct '09

Hi, There was a discussion a few months ago about a plugin for encrypting email before it hit the disk on the server, and doing transparent decryption while serving data to the client, see: http://www.dovecot.org/list/dovecot/2009-July/041262.html We have a client/user who is interested in such a plugin, and I was wondering if there has been any progress on it yet. In our particular case, server-side on-the-fly decryption would be acceptable. This service is useful in the case of a somewhat paranoid user who does not want the IT staff to have direct access to their email, without going through some major hoops (http://hushmail.com actually offers both server and client side decryption for these reasons). The way I would imagine the plugin working is public-key encryption being done on the message as it was being delivered (plug in to dovecot's deliver). Then when a client connects, the private key is decrypted with the user's password and used to decrypt the messages on the fly. Depending on performance, it may be an idea to convert messages to use symmetric with rotating keys encrypted with the public key encryption. If this were going to be done, I would think an IMAP protocol extension may be an idea so client-side encryption would be an option as well, so there would be end-to-end security.

[Dovecot] OT: IMAP folder aliases
by Patrick Ben Koetter 01 Oct '09

01 Oct '09

It seems that there is no standard for folder names that deal with typical message classes such as drafts, outbox, sent, spam etc. At least there's no common sense on a naming convention that tells how client should handle this. Worse than this, most IMAP clients auto-create folders according to their own naming convention if they don't exist. Every client introduces its own view. Users OTOH expect a single view that makes it easy for them to find their messages. They are unwilling to search in "sent", "sent-mail" or "Sent items" for "messages that have been sent". I doubt that software producers will adopt a standard naming convention if it was introduced within a useful time span. Has anyone seen an approach or a solution that solves the problem from a users point of view? A server side alias list that maps to a server standard? p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

Fair enough. But I never saved the tail when the problem occured. I can now extract this again from the info log (getting everything between 11:06 to 11:08 which should be within the problem time...). Who should I send it to? It's 181 lines to 'privatize' and I'd prefere not to send a unprivatized file to the list...

This may be enough for Timo, but its always better to give the full logs of one of these transactions - not just the dovecot error log, but full system logs, showing the message entering the system, each step of processing, and ending with the final delivery (attempt)... -- Best regards, Charles Marcus I.T.

[Dovecot] Compile dovecot 1.2.5 with managesieve patch 0.11.9?
by Seba 01 Oct '09

01 Oct '09

Hi, is it possible to compile dovecot 1.2.5 with the managesieve patch 0.11.9 which is for dovecot 1.2.4 or is it better to wait if a new managesieve patch is released? Maybe 1.2.5 will work too? Thanks, Seba
